Paper Title:
Feasibility Analysis for Large Rectangular Ingot Production by Intensive Cooling
  Abstract

Lots of heavy plate mills more than 5m have been in operation, the design of corresponding large ingots becomes crying needs. In this paper, a special method of intensive cooling outside mould has been presented and applied to a designed 80t ingot (4200mm×1100mm×2600mm). Mathematical simulation results tell us that by intensive cooling, the solidification time of the 1100mm rectangular ingot can be shortened into 120min, which is only 1/4 compare with air cooling, internal soundness can be ensured also. The intensive outside cooling process can obviously improve microstructure and preventing skull patch by increasing the thickness of solidified shell.
